It seems to me that there is probably a limit to how much heat can be generated with a pepsi can stove, and the next advance is in making better use of the...
Not really. While the Caldera Cone works very well for the pots it fits, it doesn't involve a heat exchanger. The heat exchanger does increase efficiency quite...
I've seen some heat exchangers made out of metal grids. I've also seen similar grids in overhead fluorescent lighting. I think that's where I'd start. Tim D....
Okay, so where are you going to put a heat exchanger on a Caldera setup? Seems that that is already built in--it's got space between the sides of the pot and...
Well, technically the pot itself is a heat exchanger, if you're going by the engineering definition: a device that transfers heat between two fluids. I think...
No, I'd put it on the bottom of the pot, like it belongs..... ;o) A heat exchanger usually involves fins of some type to act as radiators from the hotter...
Yup, usually some kind of fin arrangement that increase the absorption surface are of the cooler side or the radiating surface area of the hotter side (if you...
I have a few questions that maybe some of you could answer for me, if you would be so kind. #1. I ordered some of the Guyot squishy bowls online. The bowl is...
#1 - I don't understand. Were they smaller than advertised, or was it just that 16 oz sounded bigger than you thought. I went to their website and all of the...
Just out of curiosity, what lights from known manufacturers have you found that won't accept lithitums? Jerry http://www.BackpackGearTest.org : the most...
This is from the Petzl website: Do not use Lithium batteries with the following lamps TIKKA / ZIPKA range: TIKKINA / TIKKA / ZIPKA / TACTIKKA / TIKKA PLUS /...
However, Energizer apparently strenuously dispute Petzl's statement that "they can cause the lamp to overheat and possibly damage the LEDs." Also, Petzl states...
I found it interesting that the manual for my Garmin eTrex VistaCX GPS receiver also says not to use lithium batteries. I think it even voids the warranty. Tim...
it may have to do with the different battery chemisties. Energizer hold a patent on a 1.6V LI battery chemistry which is directly compatible with regular...
Ah, Petzl. I knew there was a reason I've never owned one..... ;o) Although I am surprised they are that crude and behind the times..... =o) I've used...
I've used nothing but lithitums in both my Megellans. I just got a DeLorme PN-20 but haven't had a chance to use it with anything but the alkalines that came...
That would explain it. Energizer lithiums are the only lithiums I've use in my portable stuff. Jerry http://www.BackpackGearTest.org : the most comprehensive...
How do I determine if my device is regulated or not? I checked on the Petzl site and didn't see this info, I have a Tikka Plus. Thanks. Jerry Goller...
Well, you could just buy a Princeton Tec..... ;o) The Devil made me say it...lol I honestly don't think the non-rechargeable lithium batteries will damage ...
I'm going to be in Sapphire, North Carolina (near Lake Toxaway and Cashiers) at the end of October. Does anyone know of any good hiking or backpacking...
I have a biz trip in the Seattle area, and hope to skip over to the mountains while I'm there. Hitting trail head on later afternoon of 9/19 or 9/20. Leaving...
I'm looking at the (very light!) Marmot Helium +15 850+ fill down mummy sleeping bag for use as a 3-season bag in the Southeast US, especially the Southern...
I don't know about the Helium, but I have been very happy with my Marmot bag. I never never talked to anyone who isn't. A couple comments. 1 - I would spend...
My wife has a headlamp, unfortunately she left the batteries in it for a very long time, so they have corroded and leaked, contaminating the terminals. Is...
I wouldn't trust a camping light after it has been corroded-i would discard it. I couldn't imagine my frustration with needing it in the middle of the night ...
wash it out with vinegar to neutralized the battery gunk, then water to get rid of vinegar. dry it throughly. you might want to use sandpaper or something to...
The sand paper will take the plating off the metal, assuming the corrosion hasn't already done that. The contacts will be prone to rust and oxidation (low...
